Given an N x M matrix having only positive values, we have to nullify the
matrix i.e make all entries 0.
We are given two operations
1) multiply each element of any one column at a time by 2.
2) Subtract 1 from all elements of any one row at a time
Find the minimum number of operations required to nullify the matrix.
Note: no range of input was given
